Everyone I talk to says they want to wait to have children until they're in their mid 30s. That seems a bit late to me. My mom was 20 when she had my oldest brother. I'm the youngest, and she still was 26 when she had me. I see my parents now, in their mid fourties, and I can't imagine what it would be like for them if they were taking care of kids into their fifties. How old were you when you had your first child? If you could go back, would you have waited, or started having kids earlier, or will you keep things the way they are.
